  2. Next-Gen Gap “Unfortunately, the software and computer hardware demands on these analyses are not much less than those of the large Genome Centers. From this perspective, the gap between large-scale genome centers and individual investigators may seem to be growing, not shrinking, as the next-generation platforms’ apparent promise of a ‘Genome Center in a box’ may have only been half delivered, providing data without a full suite of tools.” (Nature Methods 6, S2 - S5 (2009)) Download Data Learn *NIX Install Software and Dependencies Run Software … Wait? … Problems? Bacterial genome in < 1 week for ~ $3000 (Genome Assembly)+

  3. Three Common Methodologies in de novo Genome Analysis Display and analysis of genome annotations Quality assessment of a genome assembly Comparison and mining of genomic data from public repositories. • One or more methodologies used to address needs in three specific projects; projects used as a vehicle to develop software:

  4. Assembly Quality Assessment

  5. Assembly Analysis • Researchers should have easy access to determine quality and perform simple analysis. DNA Sequencing Centre Researcher Assembly • Delays and limits on data access exist: • - Viewers need to be installed and have specific software (e.g. Linux) or hardware requirements (e.g. RAM). • - Assembly data (multiple GBs) must be downloaded.

  6. Objective • Develop a simple assembly viewer that operates within a web-browser, allowing a researcher to rapidly analyze and access their data.

  7. Method Parser/Converter: Used python to parse, analyze, and convert assembly data into web accessible formats (HTML, JSON, JPG images) which are stored on sequence centre servers. Interface: Use browser-based interface (HTML) to dynamically access data (Javascript) on servers. Incorporates pre-existing web-technologies (JQuery, SeadragonDeepzoom AJAX). Usage: - after genome assembly, parser/converter is run on sequencing center servers - researcher accesses interface over the internet using a modern web browser

  8. Performance Parser/Converter: • Multiple platforms (Windows/OS X/Linux) • Multi-processor support. • Low memory usage (< 250Mb of memory per processor). User interface: • Client-side programming  decreased server load • Data is downloaded is on-demand  limited bandwidth users. • Sole system requirement: a modern web-browser (Firefox, Opera, Google Chrome)  ease of installation. • Low memory usage (peaks at ~ 250 Mb).

  9. The Interface • Dynamic Charts: • toggle axis value • identify points • summarize regions Assembly statistics, batch download of sequence and statistical data. • Table of contig/scaffold statistics: • Sortable/Filter by column • Access to contig sequence/quality and read sequences. • Contig Assembly: • Pan/Zoom • Identify position, read names, mismatches
